What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2
How do you find the area of a semicircle using pi?
To find the area of a semicircle, you first need the radius (r) of the semicircle. The formula for the area of a full circle is ( A = \pi r^2 ). Since a semicircle is half of a circle, you divide that area by 2: ( \text{Area of semicircle} = \frac{1}{2} \pi r^2 ). Thus, the area of the semicircle can be expressed as ( \frac{\pi r^2}{2} ).
How many cubic feet in a 12 inch by 12 inch by 1 inch area?
one twelfth. 1/12
What is the area of a sheet of 9-inch by 12-inch paper?
The area of a sheet of paper can be calculated by multiplying its length by its width. For a 9-inch by 12-inch sheet, the area is 9 inches × 12 inches, which equals 108 square inches.
How many 1 inch blocks in a 12 inch by 12 inch block?
Two measurements are indication of area. The area would be 144 square inches.

Area of a 12 inch circle?
A 12-inch circle has an area of about 113.1 square inches.
What is the area of an 6 x 9 inch oval?
A 6 x 9 inch oval is a 3 inch x 3 inch square with a semicircle of 3 inch radius at each end. The total area is, therefore, 9 + 9*pi = 27.3 sq inches. Note that an oval is NOT an ellipse.
What is the area of a circle that has a 12 inch diameter?
The area of a circle that has a 12-inch diameter is: 113.1 square inches.

one twelfth. 1/12
What is the area of the semicircle if the length of the arc of a semicircle is 10 and pi feet?
It is 27.49 units.

What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
What is the area of a semicircle when the radius is 21?
The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.
Area of 12 inch diameter circle vs 16 inch?
Area of a 12-inch circle: 113.1 square inches.Area of a 16-inch circle: 201.1 square inches.
